OpenAI confidentially submits draft S-1 to SEC, IPO timing undecided

OpenAI 向 SEC 机密提交 S-1 草案，上市时间未定

OpenAI confidentially submitted a draft S-1 registration statement to the SEC. The post does not disclose valuation, fundraising size, or IPO timing.

Why it matters: OpenAI has taken a concrete pre-IPO registration step, a capital-markets event for a foundation-model company. HKR-H/K/R all pass; valuation, proceeds, and timing are absent, but the item still clears P1.
